Abstrakt: Let ξ, ξ1, ξ2, be a sequence of independent and identically distributed random variables, and let Sn =ξ1 +…+ξn and Mn = maxk⩽n Sk. Let τ =min{n⩾1: Sn ⩽0|. We assume that ξ has a heavy-tailed distribution and negative, finite mean E(ξ) < 0. We find the asymptotics of P{Mτ ϵ (x, x + T]| as × → ∞, for a fixed, positive constant T. [ABSTRACT FROM AUTHOR]
